- Digital coax from Oppo to D8 on the G68 (currently connected to the digital multi in DVD).
- 6 analogue outs from the Oppo into the 5.1 analogue inputs on the G68.
Yep this should be fine; digital for 2 channel and analogue for multi-channel (of course what you realy need is a HD621 and scrap the analogue connections and use HDMI

)
(I am also considering connecting the stereo phono outputs from the Oppo into an analogue input (CD) on the G68 if for no other reason than to compare the quality).
I would not personaly bother with this as the DACs in G68 are much better.
I will then attempt to go into MSconfig and set up correctly!
This is very important, don't forget to add in you non-Meridian equipment in to it as well; so all the sources and connections are correct.
From reading some of the replies it would appear I do not need to set speaker distances etc. [in the Oppo] as the G68 will still look after this, can someone confirm if this is correct please?
This is correct, however it is not automatic in the G68 you will need to calibrate speaker level and distances (you will need a tape measure and a SPL meter to do this). Oh and a way of connecting your laptop to the G68). Again check out the WikI and also Google Search this site for help in the first instance.
If you wish to email me you .msf file once you have it setup [and a description off all you kit and how it is / wish it to be wired] I can check it out for you.
